What is the newest signed route designation in your state/province/prefecture?

[Duke87]

New York's would be I-781, then. I-99 was designated more recently, but there had previously been a NY 99.

Another interesting bit of perspective here would be that the following designations in New York are all newer than the newest signed designation in Connecticut:

I-99 (2014 in NY, 1998 overall)
I-781 (2012)
NY 185 (2008)
NY 747 (2007)
NY 840 (2005)
NY 598 (2004)
NY 317 (2003)
NY 825 (2002)
NY 631 (1999)
NY 890 (1998)
NY 444 (1997)




The newest designation in New Jersey is NJ 133, which opened in 1999.

Arguably the 'M56 SPUR' designation on driver location signs at J7 that went up a couple of weeks ago.

A2690 (I think) for an actual route designation on actual direction signs is the most recent, dating from last December. The A5758 also opened in 2015 on the road (rather than the planners' plan).

I don't think this year would create any new routes, but the 2017 opening of the Dunstable northern bypass looks to be creating the B440 and A5505.

I think the newest state route in PA is a bannered route, Business PA 8 in Oil City. It was introduced in 2000.

I got PA 576 in October 2006, PA 290 in 2006, and PA 760 in 2009 (replacing the northern part of PA 60 that did not become I-376).  (also used PAHighways.com)

US 202 Business in Montgomery and Bucks Counties is probably the newest being posted earlier this year.  (using the old US 202 before the 202 Parkway opened in 2012)

[bulldog1979]

For Michigan, it would be M-231, opened on October 30, 2015.

DE 279 was created along the former Elkton Road section of DE 2 back in 2013.  It was done in an attempt to make the routing situation in Newark less complicated (despite the fact that signage in town still refers to the original alignment of DE 2 from some 30 years ago).

California 905/future I-905 in the late 1980s as a replacement for what had been Route 117 in San Ysidro seems to be the winner out here, as far as newest numbered route to have never been used before to be established.   New routes from the 1990s that use older numbers: Route 7 (El Centro) and 11 (Otay Mesa/San Ysidro).  210 extension east of Route 57 might be the newest signed state route technically (dating to 1999) though it is not the establishment of newly defined numbered route.

I'm not sure there are any newly designated state routes since then, with CalTrans's tendency towards relinquishment in the decades since 905 was created.

I think the newest standalone state route designation in California is SR 11 in San Diego. Yes, it is a recycled number, but it is the newest standalone route (not an extension of another route) that I know of. It opened on March 19, 2016. It was planned starting in 1994, but signs didn't go up until this year.

[andy3175]

The newest route designation in Wyoming probably is WYO 257, the West Casper Belt Loop.

[cappicard]

I'd say I-49 in Missouri.  US 71 was officially designated as 49 in 2012.

In Kansas, probably K-12 in '92.  It was the last designation of Shawnee Mission Parkway before K-DOT reverted K-12 back to the City of Shawnee.

K-12 was also a destination for K-10 prior to 10 being made into a freeway in the late 70s.

In Indiana, the newest signed state road was State Road 931, former U.S. 31, up in St. Joseph County, signed in 2014.

It's a weird route that starts at the Marshall-St. Joseph County line, and ends up in the South Bend city limits, intersecting State Road 4 along the way.

[epzik8]

Probably Maryland Route 200, the Inter-County Connector, a toll road which I believe was planned decades ago as the "top" portion of an "outer beltway" for DC. The Connector was completed in 2014 with the opening on the link between I-95 and U.S. 1 south of Laurel.

[Bitmapped]

West Virginia's newest signed state route is WV 43, the Mon-Fayette Expressway, from 2011. There are newly constructed sections of the New River Parkway, which will be WV 125, but they aren't signed as such yet.

US 48 was first signed in WV around October 2010 when the section of Corridor H west of Moorefield opened.

[formulanone]

For Alabama, SR 382 is the newest designation, as it was placed on US 82's old alignment in Centreville in mid-2015.

SR 605 replaced a county road south of Dothan...which was 3-4 years ago?

[Zeffy]

I'll take a stab and say in New Jersey it's NJ 133.

[Mr. Matté]

I'll take a stab and say in New Jersey it's NJ 133.

Correct per Wiki for signed state highways but the AC Expressway Brigantine Connector (Route 446X) was in the mid-2000s and your favorite road, the US 206 Bypass in Hillsborough, was opened in 2013.

[SectorZ]

New Hampshire's appears to be NH 33, created when NH 101 was re-routed to Hampton in 1994.

Before that, I-393 opened in 1979, and NH 132 was re-numbered from NH 3B at some point in the 80's I believe.

[corco]

I believe it is Idaho State Highway 167.

[WillWeaverRVA]

US 460 Bus for Grundy is the most recent new designation in Virginia, AFAIK (2014).

I think VA-8 BUS in Stuart might actually be a couple months newer, appearing in either late 2014 or early 2015.

When did current VA 409 appear?

[froggie]

^ Officially designated in 2010.  Signed no later than late 2012.

[SD Mapman]

For SD... I'm really not sure. It will be SD 100 (eventually), but that's nowhere near done yet.

The newest route designation in Wyoming probably is WYO 257, the West Casper Belt Loop.

For sure, since that was just this past winter. I think the one before that was the Business Route of US 85 in Torrington in 2014 or somewhere thereabouts.

[jbnati27]

It looks like it's state route 733 for Ohio.

[PHLBOS]

It's not a "route where there never was one before" situation, but Massachusetts's newest route designation is Route 129A in Lynn, which was created in 1995 on a section of former Route 129.  This was done as a condition of re-routing Route 129 into the Downtown Lynn area.  Both the Route 129 re-routing and the new Route 129A were implemented by MassDPW at the urging of City of Lynn officials and the local legislative delegation.  Route 129A was created to appease the local businesses along the section of Route 129 to be relocated after they protested about the plan.

Owing to issues with how the signing changes were implemented, there was a long period of time where Route 129 markers were still in place along the "new" Route 129A.  And there's at least one location I'm aware of (the intersection of Eastern Avenue and Western Avenue) where a D6 'paddle' sign still has a Route 129 shield on it to this day.

Good luck to anyone attempting to follow MA 129 in that area between MA 129A's western end (near Wyoma Square) and MA 1A (Broad St.); the near non-existent signage along that part of 129 has been absolute garbage since day one.

As far as 129 signs still existing near/along 129A are concerned; there are at least two 129 trailblazer assemblies:

along MA 107/Western Ave. Southbound at Waitt St.

along MA 1A/Paradise R. Southbound prior to Eastern Ave.

A bonus - Erroneous WEST 129A trailblazer sign (should be marked as EAST 129).

No erroneous LGS' (D6/D8) regarding 129 through Lynn could be found in any current GSVs.

A lot of the 600 series county routes in my area of New Jersey were not signed or rarely signed until in the late 1990s almost all traffic-lit intersections got enhanced blades with both street name and route number on them. The ones I know off the top of my head are Camden County 626, 627, and 604. AFAIK the numbers were always assigned, they were just not signed. I know other counties had them earlier. I don't know if other counties got them even later. If we're talking about completely new routes, the first part of NJ 133 opened in 1999. I assume it was signed as soon as it was opened.

Other than that, our state legislature approved a $15 billion works package that will extend a bunch of existing highways, but not create any new ones. It's more likely that some will be removed, like SR 513 in Seattle (which is pretty much useless now).

21 years later, and they still haven't gotten it right .  At least somebody changed the D6 sign at the intersection of Eastern Ave and Western Ave to read 129A.

Hey!   

From one useless route to another, we're in need of some trimming. SR 531 doesn't even connect to a state park anymore.
